Dear all,
I've done a PPI analysis using region X as seed region to study changes in connectivity between 2 conditions, let's say A and B. I found a positive PPI comparing A to B.
A reviewer asked me to specify if this effect is driven by: 1) positive connectivity in B and greater positive connectivity in A, 2) negative connectivity in B and less negative connectivity in A.
How can I do that?
Any help would be really appreciated.
Thank's,
Marco
